You forgot to mention that instead of just spinning that gas cap right off, you should loosen it JUST a little bit first to let it vent, THEN take it off the rest of the way....Jeez, i hope nobody went and tried this your way and got hurt!!!

By the way, one small correction. I would move the grounding yourself part before the unscrewing the lid. What if vapor escapes when you unscrew the lid and then the static discharge from your body ignites it? Someone could blame you for that. I would do it to be safe :thumbup:
